I'm pretty sure this isn't the article you were thinking of, but I made my own Az/El rotor from a U-110 and a regular Ham-type rotor, with a Basic Stamp-based controller. Has both manual and automatic modes. See the pictures and links to the design documentation at the top of:

Good luck,

I am looking for an old article regarding the use of two U-110 rotors for satellite operations.
I have gone through all my old references and cannot find what I'm looking for.
Basically, it was a setup using two U-110's (or it could have been two U-100's). The homemade controller used either toggle or rocker switches and had a digital readout of AZ/EL using DVOM's. As far as I remember, it was all manual. I remember seeing this in the back of some publication, but I cannot find it.
Does anyone have any inkling of and idea what I'm talking about?
